Apple watch series 2 stuck at apple logo and not restarting
I have been using apple watch series 2 and the watch rebooted and never switched on.
Tried the hard reset by pressing the dial and home button. gives me the same result. apple logo appears and switches off. Tried to unpair the watch and unpaired it successfully on phone, now it doesn't let me to re pair as well.
Can someone please tell me what is this issue?
